Best Quality and Performance
YASDA Precision Center YBM 10T is a large size horizontal machining
center, developing a new area for high speed and high precision machining
of a large and heavy components.
The high speed positioning of 45m/min. is achieved employing twin ball
screws for each linear axis remaining YASDA’
s traditional high positioning
accuracy and the machine further increased its rigidity.
Excellent capability is achieved for high precision machining of box shape
components and large size die and molds.

Outstanding Technology that enables the heaviest job on 1000x1000mm
pallet in the world, of max. 5 tons with the highest accuracy
Y-axis twin ball screws
1
X-axis twin ball screws
Twin ball screws (X / Y / Z axis)
By using twin ball screws on each linear axis, high speed positioning of 45m/min. is achieved without
sacrificing high positioning accuracy and machine rigidity.
2
B-axis employed big diameter 3 roller bearing
By using the big diameter 3 roller bearing on B-axis highly accurate positioning of max. 5 tons on
1000x1000mm pallet rotation is achieved with high speed.
3
Improved vertical movement and straightness of the spindle head
The spindle head is positioned in the center of the two ball screws that improved geometrical accuracy of
Y-axis and stable vertical movement of the spindle head.

Highly rigid machine construction that supports
reliability and stability of the precision job
The steel bed of simple“H”configuration
with two 90mm thick longitudinal frames
and 40mm thick flat surface frame
enabled outstanding rigidity.
Each solid steel sheet of the frame has an
equal heat capacity at any point, therefore
the bed is free from any strain caused by
the room temperature changes, and
assure high stability of geometrical
40mm
accuracy.
90mm
The large column with a double housing structure
ensures outstanding thermal control and machine rigidity.
Each housing is designed in the shape of box formed by
double walls and ribs are arranged in the housing.
Column (Y-axis) guide ways
Y-axis guide ways are mounted
in a slight concave configuration
in order the spindle head to
obtain equal preload at any
position of Y-axis.
Combination
with the roller way bearings on
the both sides of the spindle
head, it minimizes yawing error
of the spindle head and stable
high positioning accuracy is
ensured.

Highly rigid 120mm thickness pallet and the curvic
coupling of large diameter ensure high accuracy of
work pieces for long years.
①The pallet is made of high quality cast iron, and
its top surface is carefully hand scraped to support
micron meter accuracy of work piece.
②The bottom of the pallet is flat, and available for
any kinds of transportation system, like automatic
warehouse or FMS system.
③Large diameter curvic coupling is employed on
the pallet chucking system. This curvic coupling
has 72 teeth with a 30 degree engaging angle on
each tooth which engage without any backlash and
automatically locates the center of the pallet.
CLEANING NOZZLE FOR CURVIC COUPLING
Air cleaning nozzle is provided to the base of each
tooth of the curvic coupling.
The surface of the
teeth is kept clean by ejected air from the nozzle,
and it ensures high chucking accuracy all the time.

YASDA’s exclusive preload self-adjusting system technology provides
a large preload at low speed, and reduces the preload according to the
heat generated by higher spindle speed. This mechanism creates a
clear advantage over the conventional fixed type preload system.
①Appropriate preload for full range of the spindle speed help achieve
the both heavy duty cutting at low spindle speed and highly accurate
rotation at high spindle speed.
②The spindle cartridge and the spindle motor are connected co-axially
by a diaphragm coupling to achieve highly accurate rotation of the
spindle at the full range of its rotation speed.
③Variety of machining is possible by YASDA’s spindle, such as highly
accurate turn boring, heavy duty machining, high speed machining on
the hardened steel, helical end milling, back face milling, and so on.

THERMAL DISTORTION STABILIZING SYSTEM（Option）
Thermal distortion of the machine in geometry can occur
when the room temperature changes in a short time,
which is critical for high accuracy job.
YASDA Thermal distortion stabilizing system enables to
keep the machine geometry stable against changes of the
room
temperature,
that
circulates
a
temperature
controlled oil, ±0.2°
C to room temperature, throughout the
main structure of the machine.
Thermal distortion stabilizing oil to the bed
HEAT TRANSMISSION PREVENTION ON THE BED
The guide ways and the bed are
protected with a cover so that the
warmed coolant after machining
and chips dropped cannot affect on
the thermal deformation of these
main components.
COOLING SYSTEM OF BALL SCREW BRACKET
Cooling oil circulates through the oil jacket in the ball screw
bracket that prevents heat
generation of the thrust
bearing and helps stabilize
machine geometry during
its running.
